5-Channel Power Amplifier
The MM7055 is expertly crafted to meet all your high powered needs. It's designed to deliver consistent and precise power wherever and however you need it.
Key Features
- Power for your system: The MM7055 power amplifier produces 140 watts of high current output from each of its five channels.
- The many faces of excellence: In practical terms, the MM7055 is ideal for a “5.1” home theatre system, whether based on a moderately powered receiver or a surround sound processor.
- More Marantz power: A massive power supply includes a multiple-secondary EI-core transformer and over 65,000 µF of custom-designed energy storage capacity.
- Cool machine, warm sounds: Physically, the MM7055’s output stages mount on an extruded aluminium “thermal tunnel” for efficient heat dissipation.

Flexible Connections
Balanced inputs and single-ended RCA inputs are both supported, and you can choose either type of input for each channel, individually, for easy and flexible connectivity. Audiophile grade, gold-plated four-way binding post speaker terminals insure tight connections to your choice of speaker wire.
